I looked up your account using the email address you've used to sign in here and I don't see any registered products. Do you have your serial # written down or saved somewhere we you can retrieve it? If so, you can download an installer here and use your serial # to activate: http://www.adobe.com/downloads/other-...

If you've lost an activation because of a hardware failure and the system no longer runs, go to this page and work with a chat agent. They should be able to restore your activation: http://helpx.adobe.com/x-productkb/po...

If you don't have your serial #, there's not a way for us to look up that information if the product wasn't registered.
